SPECIFICATION forming part of Letters Patent No. 253,289, dated February 7, 1882.

Application filed November 28, 1881.

To all whom it may concern:

Be it known that I, BENJAMIN F. HUDsoN, a citizen of the United States, residing at Bear Ureek,in the county of Parker and State of Texas, have invented certain new and useful Improvements in Locomotives; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to the letters and figures of reference marked thereon,which form a part of this specification.

My invention relates to'a locomotive running-gear and motive-power connection; and the novelty consists in the construction, arrangement, and adaptation of parts, as will be more fully hereinafter set forth, and specifically pointed out inthe claim.

The object of the invention is to attain a maximum of speed with a min mum of power; and to this end the invention consists essentially in four riding-wheels upon either side of the locomotive, each of which is provided with a circular head projecting outward, the said riding-wheels being arranged in pairs, and being provided with the ordinary holdingflanges. A drivingwheel upon either side bears upon the circular heads of each pair of riding-wheels, and a similar wheel is connected thereto by link-and-pitman connection. The weight of the cab, boiler, &c., rests upon the frame in which the driving-wheels are journaled, and insures the proper amount of friction upon the friction-heads of the ridingwheels. The driving-wheels receive their motive power from a piston-connection upon each side, the piston of which operates in a steam-cylinder in the ordinary manner. It will be understood that the connections upon each side are alike, except that the eccentric connections with the driving-wheels are arranged at right angles, or nearly so, so as to overcome the dead-center. I employ a loose or pivotal connection between the drivingwheels upon each side, and at the pivot Iem-. ploy a carriage which operates in inclined guides, the incline being so arranged as to de- (No model.)

scribe a line equidistant from below the center of motion of the front driving-wheels to a point above the rear driving-wheels.

The invention is fully illustrated in the accompanying drawing, which forms a part of this specification, and in which the figure is a side elevation.

To enable others skilled in the art to which the invention relates to make and use the same, I will describe the construction and mode of operation, referring for this purpose to the said drawing, in which similar letters of reference indicate like parts.

A represents the truck-frame, in which are properly journaled the riding-wheels A, and B an upper frame, in which are journaled the shafts O of the driving-wheels 0. An arm or connection, D, connects with the forward driving-wheel by a pitman or arm, E, and to the rearward driving-wheel by a pitman or arm, F.

At the pivot f, between the arm D and arm F, is loosely connected a piston-rod, G, which receives its reciprocal motion from inclined steam-cylinders H, which connect withthe steam-generator in any ordinary manner. Inclined guides J J, attached to the frame B, carry the reciprocating carriages I I, to which connections are attached.

The riding-wheels are provided with circular or cylindrical heads K, upon which the driving-wheels bear, and which are revolved by reason of the friction, as is obvious.

Modifications in details of construction may be made without departing from the principle or sacrificing the advantages of my invention, the essential features of which consist in the riding and driving wheels, the pitmanand-link connections, the inclined guideways,

The frame 13, having inclined guides J J, and the reciprocating carriages I I, connected by the pitman E, the arms D F, connecting the carriages I I to the driving-wheels, respectively, and the piston-rod Gr, all combined with the wheels 0', cylinder H, and ridingwheels A, having circular bearings K for the driving-wheels, as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.

BEN. F. HUDSON.
